煤矿固体废弃物的危害与治理

Hazards and Treatment of Solid Waste in Coal Mines

煤炭开采及洗选中容易产生较多的固体废弃物,如果缺乏有效治理就会造成较大的环境污染,因此需要做好对固废的针对性处理。为此,基于A矿的煤矸石性质,先进行煤矸石危害分析,明确煤矸石堆积隐患,然后从固体废弃物堆置处理、生态环境修复等方面进行固体废弃物危害治理的分析,并从采空区回填、发电燃料、建筑材料等方面提出了煤矸石的利用方向,期望对煤矸石的危害治理和回收利用能促使矿企实现可持续发展。

Coal mining and washing is easy to produce more solid waste,and the lack of effective treatment will cause greater environmental pollution,so it is necessary to do a good job of solid waste treatment.Therefore,based on the nature of coal gangue in A Coal Mine,the hazard analysis of coal gangue was first carried out to identify the hidden danger of coal gangue accumulation,then the solid waste hazard management was analyzed from the aspects of solid waste stacking,ecological environment restoration,etc.,and the utilization direction of coal gangue was proposed from the aspects of gob backfilling,power generation fuel and building materials.It is expected that the harmful treatment and recyclable application of coal gangue can promote the sustainable development of mining enterprises.
